本考案は水耕栽培用支持体に関する。詳細には、水耕栽培される植物が病原菌 やウイルスなどの微生物に感染するのを確実に防止できる水耕栽培用支持体に関 する。 The present invention relates to a hydroponic support. More specifically, the present invention relates to a hydroponic support that can reliably prevent a hydroponic plant from being infected with microorganisms such as pathogens and viruses.

【従来の技術】[Prior Art]

従来、水耕栽培用支持体としては特開平2−84118号公報に示されたもの がある。この水耕栽培用支持体は、輝緑岩などの複数の鉱石とコークスとを混合 し、これを高炉で溶融させ、遠心力の作用で均一な細かい繊維状とすることによ り得られるロックウールを用い、これをマット状やブロック状に成形したもので ある。この水耕栽培用支持体に植物が根付いて根が該支持体内に伸び、支持体内 を水耕養液が通過することにより植物が養液を根から吸収し成育するようになっ ていた。この支持体にあっては、断熱性が高く優れた保温性を有すると共に、該 支持体のポーラスな構造に由来して通気性、浸透性、水分保持性が良く、腐蝕性 がなく、しかも高温で製造されることから無菌であり、植物の水耕栽培の根付け に適した材料として広く活用されていた。 Conventionally, as a support for hydroponic culture, there is one disclosed in JP-A-2-84118. This hydroponic support is a lock obtained by mixing coke with a plurality of ores such as diabase and melting them in a blast furnace to form a uniform fine fiber by the action of centrifugal force. Wool is used and is formed into a mat or block. Plants were rooted on the hydroponic support, the roots extended into the support, and the hydroponic solution passed through the support, whereby the plant absorbed the nutrient solution from the roots and grew. This support has high heat insulation and excellent heat retention, and due to the porous structure of the support, has good breathability, permeability, and water retention, is not corrosive, and has high temperature. Since it is manufactured in Japan, it is sterile and widely used as a material suitable for rooting hydroponics of plants.

【0003】 又、別の水耕栽培用支持体としては特開平2−86716号公報に示されたも のがある。この水耕栽培用支持体は板状に成形された不織布からなるものであり 、この多孔質な板状の不織布層に植物が根付き成育するようになっていた。この 水耕栽培用支持体にあっても、上記ロックウール製支持体と同様に保温性と共に 、そのポーラスな構造により通気性、浸透性、水分保持性が良く、腐蝕性がない といった植物の水耕栽培の根付け用として優れた性能を持つ材料であった。Further, as another support for hydroponic culture, there is one disclosed in Japanese Patent Application Laid-Open No. 2-86716. The hydroponic support is composed of a non-woven fabric formed in a plate shape, and the plant was adapted to grow on the porous plate-shaped non-woven fabric layer. This hydroponic support also has the same heat-retaining property as the rockwool support, and its porous structure has good breathability, permeability, and water retention, and is not corrosive. It was a material with excellent performance for rooting in tillage.

【0004】 これら水耕栽培用支持体は、図3及び図4に示すように、水耕栽培槽2に取り 付けられ、この水耕栽培槽2内に水耕養液を循環させることにより、植物3は水 耕栽培用支持体1を通して水耕栽培槽2内を循環する水耕養液を吸収し成育する ようになっていた。As shown in FIGS. 3 and 4, these hydroponic culture supports are attached to a hydroponic cultivation tank 2, and by circulating a hydroponic solution in the hydroponic cultivation tank 2, The plant 3 was adapted to absorb the hydroponic liquid circulating in the hydroponic tank 2 through the hydroponic support 1 to grow.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記水耕栽培用支持体を用いて植物の栽培を行っていく過程で、一の植物が病 原菌やウイルスなどの微生物に侵されると、この植物と接触した水耕養液は他の 植物へも循環するようになっていることから、他の植物も水耕養液を通して微生 物に感染し侵されることになる。又、水耕栽培槽内を循環させる水耕養液中に微 生物が含まれていることもあるが、この場合も同じく各支持体を通過する水耕養 液を通して植物が微生物に感染し侵されることになる。 When one plant is invaded by microorganisms such as pathogens and viruses in the process of cultivating the plant using the above hydroponic support, the hydroponic solution contacted with this plant causes the other plant to grow. Since it also circulates to other plants, other plants will also be infected and infested by micro-organisms through hydroponics. Microorganisms may be contained in the hydroponic solution circulated in the hydroponic tank, but in this case as well, the plant is infected with microorganisms and invaded through the hydroponic solution passing through each support. Will be done.

【0006】 このような水耕養液を通しての微生物感染を防止するため、水耕養液中に殺菌 剤や防除剤を添加するという対策が採られてはいるが、これらの薬剤は特定の種 類の植物の特定の病気(微生物)にしか効果がなく汎用性に乏しいものであった 。又、水耕養液中に殺菌剤や防除剤を添加するという方法では、水耕栽培が水耕 栽培槽内に水耕養液を循環させて行なうものであるため、薬剤の効果が十分に持 続せず、定期的に補充しなければならないという煩雑さがあった。更に、これら の薬剤には人体に有害なものもあった。[0006] In order to prevent microbial infection through such a hydroponic solution, measures have been taken to add a bactericidal agent or a control agent to the hydroponic solution, but these agents have specific species. It was effective only against specific diseases (microorganisms) of plants of the same kind and was poor in versatility. In addition, in the method of adding a bactericide or a control agent to the hydroponic solution, hydroponics is carried out by circulating the hydroponic solution in the hydroponic tank, so that the effect of the drug is not sufficient. There was a complication that it had to be replenished regularly without sustaining it. Furthermore, some of these drugs are harmful to the human body.

【0007】 本考案は、このような課題に鑑みなされたものであり、水耕栽培される植物が 病原菌やウイルスなどの微生物に感染するのを確実に防止できる水耕栽培用支持 体を提供することを目的とするものである。The present invention has been made in view of the above problems, and provides a support for hydroponic cultivation, which can reliably prevent a hydroponic plant from being infected with microorganisms such as pathogens and viruses. The purpose is that.

【課題を解決するための手段及び作用】[Means and Actions for Solving the Problems]

上記目的を達成するため、請求項1記載の考案は、ピリジニウム基を有し、か つ水に不溶又は難溶の微生物吸着樹脂を含有する多孔質基材よりなることを特徴 とする水耕栽培用支持体をその要旨とした。 In order to achieve the above-mentioned object, the device according to claim 1 is a hydroponic culture characterized by comprising a porous substrate having a pyridinium group and containing a water-insoluble or sparingly soluble microbial adsorption resin. The support was used as the gist.

【0009】 本考案の微生物吸着樹脂としては、ハロゲン化されたピリジニウム基を分子内 に有し、かつ水に不溶又は難溶のものであればどんなものであっても良い。この ような微生物吸着樹脂としては、特公昭62−41641号公報や特開平1−2 07141号公報に示された4−ビニルピリジンと架橋性ジビニル系単量体とを 共重合させた後、これにハロゲン化物を作用させて4級化処理することにより得 られる高分子化合物や、特開平3−174419号公報に示された4−ビニルピ リジンとモノビニルモノマーとを共重合し、4級化処理することにより得られる 高分子化合物等を挙げることができる。これらの微生物吸着樹脂における微生物 吸着能は、該樹脂が分子内に有するところのピリジニウム基が正に帯電しており 、一般に微生物の細胞表面は負に帯電していることから、これらピリジニウム基 と微生物との間の電気的な相互作用によって発現されるものと推定される。The microorganism adsorbing resin of the present invention may be any resin as long as it has a halogenated pyridinium group in its molecule and is insoluble or hardly soluble in water. As such a microorganism-adsorbing resin, 4-vinylpyridine and a crosslinkable divinyl-based monomer disclosed in JP-B-62-41641 and JP-A-1-207141 are copolymerized and then A polymer compound obtained by subjecting a halide to a quaternization treatment and a copolymerization of 4-vinylpyridine and monovinyl monomer disclosed in JP-A-3-174419 to quaternization treatment. The polymer compound etc. which are obtained by this can be mentioned. The microbial adsorption capacity of these microbial adsorption resins is that the pyridinium group contained in the molecule of the resin is positively charged, and generally the cell surface of the microorganism is negatively charged. It is presumed that it is expressed by an electrical interaction between and.

【0010】 多孔質基材としては、通気性、浸透性に富み、植物の根が基材内部に伸びて容 易に定着できる程度の多孔質なものであって、上記微生物吸着剤を含有するもの あれば特に限定されるものではない。このような多孔質基材としては、例えばレ ーヨン、コットン、ポリアミド、ポリエチレン、ポリプロピレンなどの繊維を織 成又は編成して成る織物や編物、これら繊維を構成繊維とする不織布などの構成 繊維表面に特開平3−174419号公報に示された微生物吸着樹脂を付着した もの、或いは上記織物や編物、不織布の構成繊維表面に4−ビニルピリジンと架 橋性ジビニル系単量体とを付着した後これらを共重合させ4級化処理したもの、 特公昭62−41641号公報や特開平1−207141号公報に示された微生 物吸着樹脂であってビーズ状或いは繊維状に成形されたものをパルプや鉱石、合 成樹脂などの粉砕物中に混合しこれらを接着剤で結合させて成るもの、上記ビー ズ状或いは繊維状の微生物吸着樹脂相互を接着剤で結合してポーラスな構造体に 成形したもの等を挙げることができる。又、従来より水耕栽培用支持体として使 用されているものに微生物吸着樹脂を含浸或いはコーティングすることによって 得られるものであってもよい。又、多孔質基材は、植物が十分に根を生やすこと ができるよう見かけ密度が0.2g/cm3 以下の比較的粗い構造のものであり 、かつ一定の厚みを有するものが望ましい。The porous substrate is a porous substrate that is highly breathable and permeable, and has a plant root that extends to the inside of the substrate and can easily settle therein, and contains the above-mentioned microorganism adsorbent. There is no particular limitation as long as there is one. Examples of such a porous substrate include a woven fabric or a knitted fabric formed by weaving or knitting fibers such as rayon, cotton, polyamide, polyethylene, polypropylene, and the like on the surface of constituent fibers such as non-woven fabric having these fibers as constituent fibers. Those to which the microorganism adsorbing resin described in JP-A-3-174419 is adhered, or 4-vinylpyridine and the crosslinkable divinyl-based monomer are adhered to the surface of the constituent fibers of the above-mentioned woven fabric, knitted fabric, and non-woven fabric. Which has been quaternized by copolymerization with styrene, and which is a fine particle adsorbing resin shown in JP-B-62-41641 and JP-A-1-207141, which is molded into beads or fibers, is pulp. A mixture of crushed materials such as ores, synthetic resins, etc., which are mixed in a pulverized product and bonded with an adhesive. Combined those that have been molded into porous structures, and the like. Further, it may be obtained by impregnating or coating a microorganism-adsorbing resin on a material that has been conventionally used as a support for hydroponic cultivation. Further, the porous substrate is preferably one having a relatively coarse structure with an apparent density of 0.2 g / cm 3 or less so that the plant can sufficiently grow roots and having a certain thickness.

【0011】 多孔質基材に対する微生物吸着樹脂の含有量としては特に限定されないが、基 材に対し0.01〜20wt%の範囲のものが微生物吸着力が高く、かつ経済的 である。20wt%を越える多量の微生物吸着樹脂を含有する場合には、樹脂の 使用量が増す割には吸着効果は上がらず、不経済となる。The content of the microbial adsorbent resin with respect to the porous substrate is not particularly limited, but those having a range of 0.01 to 20 wt% with respect to the base material have high microbial adsorbability and are economical. When a large amount of the microorganism-adsorbing resin exceeding 20 wt% is contained, the adsorbing effect does not increase even if the amount of the resin used increases, which is uneconomical.

【0012】 このように構成された水耕栽培用支持体にあっては、植物の栽培を行っていく 過程で、一の植物が病原菌やウイルスなどの微生物に侵されたとしても、この植 物が根付いている水耕栽培用支持体に含まれる微生物吸着樹脂が微生物を吸着し 、水耕養液中に微生物が流れ出ることがない。又、水耕栽培槽内を循環させる水 耕養液中に微生物が含まれていても、支持体に含まれる微生物吸着樹脂が水耕養 液中の微生物を吸着するため、水耕養液を通して植物が微生物に感染し侵される こともない。In the hydroponic support thus constructed, even if one plant is invaded by microorganisms such as pathogens and viruses during the process of cultivating the plant, The microorganism-adsorbing resin contained in the hydroponic support having roots adsorbs the microorganisms, and the microorganisms do not flow into the hydroponic solution. In addition, even if microorganisms are contained in the hydroponic solution circulating in the hydroponic tank, the microbial adsorbent resin contained in the support will adsorb the microorganisms in the hydroponic solution, so The plant is not infected with microorganisms and is not infested.

【0013】 尚、多孔質基材は、形態保持、取り扱い性という点から、基材内部の見かけ密 度を0.2g/cm3 以下の比較的粗い構造とし、これに対し水耕養液が通過す る基材表層部の見かけ密度を高く設ける(具体的には0.2〜0.8g/cm3 の範囲)ようにしても良い。これにより、多孔質基材の粗い構造となっている基 材内部には植物が容易に根を生やすことができ、一方基材内部に対し密な構造と なっている表層部は、該基材の形状を保持し、水耕養液の通過に伴う水圧、その 他外力に対抗し得るようになる。又、基材表層部によって基材内に根付いた植物 が保持されることになるため、取り扱い時に植物が基材から抜け出てしまうこと もない。尚、この多孔質基材は、該多孔質基材が繊維を用いて作られたものにあ っては多孔質体の周囲から圧力を加えることにより表層部分の密度を高めて表層 部を設けても良いし、密度の高い別の繊維シートで多孔質体表面を被覆して表層 部を設けても良い。The porous base material has a relatively rough structure with an apparent density of 0.2 g / cm 3 or less inside the base material from the viewpoint of shape retention and handleability. The apparent density of the surface layer of the substrate passing therethrough may be set high (specifically, in the range of 0.2 to 0.8 g / cm 3 ). As a result, plants can easily grow roots inside the base material having a rough structure of the porous base material, while the surface layer portion having a dense structure inside the base material is It retains its shape and can resist the water pressure and other external forces that accompany the passage of the hydroponic solution. Further, since the plant rooted in the substrate is retained by the substrate surface layer, the plant does not come out of the substrate during handling. When the porous substrate is made of fibers, the surface layer is provided by increasing the density of the surface layer by applying pressure from the periphery of the porous body. Alternatively, the surface layer portion may be provided by coating the surface of the porous body with another fiber sheet having a high density.

【0014】 尚、本考案の微生物吸着樹脂と共に殺菌剤を多孔質基材に含ませても良く、こ の場合、微生物吸着能と共に殺菌性能をも備えた水耕栽培用支持体を得ることが できる。殺菌剤としては、例えば水不溶性のゼオライトを殺菌性を有する金属イ オンで置換した抗菌性ゼオライト、ポリビニル、ポリアクリレート、ポリエステ ル、ポリアミドなどのポリマー鎖にピグアナイドまたは第4アンモニウム塩を固 定化したポリマー型固定化殺菌剤、3−(トリメトキシシリル)−プロピルトリ メチルオクタデシルアンモニウムクロライドなどのシリコーン型固定化殺菌剤な どが好適に使用できる。A bactericidal agent may be included in the porous substrate together with the microbial adsorbent resin of the present invention, and in this case, a support for hydroponic cultivation having a bactericidal ability as well as a microbial adsorbing ability can be obtained. it can. As the bactericide, for example, a guanide or a quaternary ammonium salt is immobilized on a polymer chain of an antibacterial zeolite obtained by substituting a water-insoluble zeolite with a metal ion having bactericidal property, polyvinyl, polyacrylate, polyester, polyamide, etc. Polymer type fixed bactericides, silicone type fixed bactericides such as 3- (trimethoxysilyl) -propyltrimethyloctadecyl ammonium chloride can be preferably used.

【0015】 又、本考案の水耕栽培用支持体に定期的に紫外線を照射して、水耕栽培用支持 体に吸着された微生物を殺菌するようにしてもよい。Further, the hydroponic support of the present invention may be irradiated with ultraviolet rays periodically to sterilize the microorganisms adsorbed on the hydroponic support.

【実施例】【Example】

以下、本考案を実施例に従って詳細に説明する。 実施例1 4−ビニルピリジンとスチレンとを30:70モルの割合で共重合した後、4 −ビニルピリジンと等モルのベンジルブロミドで4級化処理してピリジニウム基 を有する微生物吸着樹脂を得た。 Hereinafter, the present invention will be described in detail according to embodiments. Example 1 4-Vinylpyridine and styrene were copolymerized at a ratio of 30:70, and then quaternized with 4-vinylpyridine and an equimolar amount of benzyl bromide to obtain a microorganism adsorbing resin having a pyridinium group. ..

【0017】 一方、ポリエステル繊維50重量%とレーヨン繊維50重量%とからなる繊維 ウェブにアクリルバインダーをスプレー含浸した見かけ密度0.04g/cm3 の不織布からブロック状の支持体を作製し、この支持体に上記の微生物吸着樹脂 を溶解したエタノール溶液を含浸した後、75℃で乾燥して図1に示す水耕栽培 用支持体11を得た。なお、この場合の不織布に対する微生物吸着樹脂の付着量 は2.0%重量であった。On the other hand, a block-shaped support is prepared from a nonwoven fabric having an apparent density of 0.04 g / cm 3 obtained by spray impregnating a fibrous web composed of 50% by weight of polyester fiber and 50% by weight of rayon fiber with an acrylic binder. The body was impregnated with the above ethanol solution in which the microorganism adsorbing resin was dissolved and then dried at 75 ° C. to obtain the hydroponic support 11 shown in FIG. In this case, the amount of the microorganism adsorbing resin attached to the nonwoven fabric was 2.0% by weight.

【0018】 実施例2 4−ビニルピリジン3g、ジビニルベンゼン0.05g、アゾビスイソブチロ ニトリル0.03g及びトルエン300mlを反応容器に入れ、この容器中に、 レーヨン繊維からなる繊維ウェブを水流絡合してなる不織布 (目付100g/m2 、厚さ0.4mm)を入れて浸漬した。その後、室温でト ルエンを蒸発させて、不織布の構成繊維表面に4−ビニルピリジン、ジビニルベ ンゼン、及びアゾビスイソブチロニトリルを付着させた。この後、80℃の温度 で5時間、恒温器中に静置して、不織布の構成繊維表面で4−ビニルピリジンと ジビニルベンゼンとを共重合させた。Example 2 3 g of 4-vinylpyridine, 0.05 g of divinylbenzene, 0.03 g of azobisisobutyronitrile and 300 ml of toluene were placed in a reaction vessel, and a fiber web made of rayon fiber was hydro-entangled in the vessel. A non-woven fabric (unit weight: 100 g / m 2 , thickness: 0.4 mm) formed by putting together was put and immersed. Then, toluene was evaporated at room temperature to deposit 4-vinylpyridine, divinylbenzene, and azobisisobutyronitrile on the surface of the constituent fibers of the nonwoven fabric. Then, the mixture was allowed to stand in an incubator at a temperature of 80 ° C. for 5 hours to copolymerize 4-vinylpyridine and divinylbenzene on the surface of the constituent fibers of the nonwoven fabric.

【0019】 次いで、この不織布を反応容器に入れ、同容器内に臭化ベンジルとトルエンを 加えて80℃で6時間反応させてビニル系共重合体を4級化処理し、臭化ベンジ ルにより4級化されたピリジニウム基を有し、かつ架橋構造を有する微生物吸着 樹脂を不織布の構成繊維表面に付着させた。この場合の不織布に対する樹脂の付 着量は2.0重量%であった。Next, this non-woven fabric was placed in a reaction vessel, benzyl bromide and toluene were added to the vessel, and the mixture was reacted at 80 ° C. for 6 hours to quaternize the vinyl-based copolymer, and then treated with benzyl bromide. A microorganism adsorbing resin having a quaternized pyridinium group and having a crosslinked structure was attached to the surface of the constituent fibers of the nonwoven fabric. In this case, the amount of resin attached to the nonwoven fabric was 2.0% by weight.

【0020】 一方、ポリエステル繊維50重量%とレーヨン繊維50重量%とからなる繊維 ウェブにアクリルバインダーをスプレー含浸した見かけ密度0.04g/cm3 の不織布からブロック状の支持体を作製し、この支持体の表面に、上記の微生物 吸着樹脂を構成繊維表面に付着させた不織布12を貼り付けて図2に示す水耕栽 培用支持体を得た。On the other hand, a block-shaped support was prepared from a nonwoven fabric having an apparent density of 0.04 g / cm 3 obtained by spray impregnating a fibrous web composed of 50% by weight of polyester fiber and 50% by weight of rayon fiber with an acrylic binder, and supporting this. On the surface of the body, the non-woven fabric 12 having the above-mentioned microorganism adsorbing resin attached to the surface of the constituent fibers was attached to obtain the support for hydroponic cultivation shown in FIG.

【0021】 実施例1及び実施例2において得られた水耕栽培用支持体11を水耕栽培槽( 図示しない)に取付け、これにキュウリの苗(双葉)13を植付けたものを各々 10個用意した。一方、キュウリ立枯病菌(Pythium aphanide rmatum Fitzpatrick 株番号 MAFF03−05567) をV−8ジュース寒天培地で培養し、遊走子のうを確認した後、培地ごと上記水 耕栽培槽の水耕養液中に入れた。その結果、実施例1及び実施例2のいずれの水 耕栽培用支持体11に植えたキュウリの苗も立ち枯れず、キュウリ立枯病菌には 感染しなかった。The hydroponic support 11 obtained in each of Examples 1 and 2 was attached to a hydroponic cultivation tank (not shown), and 10 cucumber seedlings (bileaflets) 13 were planted on each of them. I prepared. On the other hand, cucumber wilt pathogen (Pythium aphanide rmatum Fitzpatrick strain number MAFF03-05567) was cultivated in a V-8 juice agar medium, and after confirming zoospores, the medium was cultured in the hydroponic solution in the hydroponics tank. I put it in. As a result, the cucumber seedlings planted on the hydroponic support 11 of both Example 1 and Example 2 did not die, and the cucumber wilt bacterium was not infected.

【考案の効果】[Effect of the device]

上記構成を備えたことにより、請求項1記載の水耕栽培用支持体にあっては、 水耕養液中の微生物を多孔質基材に含まれる微生物吸着樹脂が確実に吸着保持す ることから、水耕養液を通して植物が微生物に感染し侵されることがない。又、 この水耕栽培用支持体にあっては、微生物吸着樹脂の正に帯電するピリジニウム 基と負に帯電する微生物との電気的な相互作用を利用して微生物を吸着し保持す るようになっていることから、従来の水耕養液中に殺菌剤や防除剤を添加する方 法のように特定の植物や特定の病気にしか効果が無いということはなく汎用性に 富む。更に、この水耕栽培用支持体にあっては、該水耕栽培用支持体に含まれる 微生物吸着樹脂が水に不溶又は難溶であるため、使用時に水耕養液中に溶出する ことが無く定期的に薬剤を補充するといった煩雑さがない。又人体に害を与える こともない。 By providing the above-mentioned structure, in the hydroponic support according to claim 1, the microorganisms in the hydroponic solution can be surely adsorbed and held by the microorganism adsorbing resin contained in the porous substrate. Therefore, the plant is not infected and invaded by microorganisms through the hydroponic solution. In addition, in the hydroponic support, the microorganism is adsorbed and retained by utilizing the electrical interaction between the positively charged pyridinium group of the microorganism adsorption resin and the negatively charged microorganism. Therefore, it is versatile because it is not effective against only specific plants and specific diseases like the conventional method of adding fungicides and control agents to hydroponics. Furthermore, in this hydroponic support, since the microbial adsorbent resin contained in the hydroponic support is insoluble or sparingly soluble in water, it may elute into the hydroponic solution at the time of use. There is no complexity of regularly replenishing drugs. It also does not harm the human body.

【0023】 請求項2記載の水耕栽培用支持体にあっては、多孔質基材表層部の見かけ密度 を多孔質基材内部の見かけ密度よりも高く設けたことから、多孔質基材の粗い構 造となっている基材内部には植物が容易に根を生やすことができ、一方基材内部 に対し密な構造となっている表層部は、該基材の形状を保持し、水耕養液の通過 に伴う水圧、その他外力に対抗し得るようになる。又、基材表層部によって基材 内に根付いた植物が保持されることになるため、取り扱い時に植物が基材から抜 け出てしまうこともない。In the support for hydroponic culture according to claim 2, since the apparent density of the surface layer of the porous base material is set higher than the apparent density inside the porous base material, Plants can easily grow roots inside the base material that has a rough structure, while the surface layer that has a dense structure inside the base material retains the shape of the base material and It becomes possible to counter the water pressure and other external forces that accompany the passage of the nutrient solution. In addition, since the plant rooted in the substrate is retained by the substrate surface layer, the plant does not fall out of the substrate during handling.

【0024】 請求項3記載の水耕栽培用支持体にあっては、微生物吸着樹脂と共に殺菌剤が 含まれていることから、微生物を吸着保持するのみならず支持体内部で殺菌して しまうため、他の植物への感染防止効果をより向上させることができる。In the hydroponic support according to claim 3, since the bactericidal agent is contained together with the microorganism adsorbing resin, not only the microorganisms are adsorbed and held but also sterilized inside the support. , The effect of preventing infection of other plants can be further improved.
